iphone simulator shaking has no function

Hello everyone I hoped to test the shaking functio开发者_JS百科n on simulator, so in the Hardware menu, I choose Shake Gesture. But nothing happened, what wrong?

Welcome any comment

Thanks

Clicking "Shake Gesture" in the iPhone simulator doesn't play an animation—perhaps this is why it seems not to be doing anything?

You can receive notification of shake events in your code by implementing motionEnded:withEvent: in a UIResponder subclass. For example, if you were to create a custom UIWindow subclass:

// ShakeWindow.h
@interface ShakeWindow : UIWindow
@end

// ShakeWindow.m
#import "ShakeWindow.h"

@implementation ShakeWindow

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
  if (motion == UIEventSubtypeMotionShake) {
    NSLog(@"Shake!");
  }
}

@end

For more information, see the Motion Events section of Apple's Event Handling Guide for iOS.

-(void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [self becomeFirstResponder];
}

-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {

    if (motion == UIEventSubtypeMotionShake) {
        NSLog(@"shake");
        //your code
    }

}
